Concern has developed at the northern Indiana National Weather Service (NWS) office about a risk of severe weather east of Interstate 69 between midnight EDT tonight and 6 a.m. EDT tomorrow. Meteorologist have indicated there’s even a low chance of isolated tornadoes. Below is a series of tweets the NWS office sent this afternoon and evening. Heed the advice in these tweets, especially making sure that you’ll be awakened (e.g. by a NOAA Weather Radio) if dangerous weather pops up while you’re asleep.
See also the updated “Hazardous Weather Outlook” from 8:06 p.m. EDT that I pasted below the tweets.
For storm spotters who want to know the meteorology, here’s a relevant portion of an “Area Forecast Discussion:”
MODELS SUGGESTING A THREAT FOR LOW TOPPED SUPERCELLS OR SMALL BOWING SEGMENTS. IT NEEDS TO BE STRESSED THAT THIS IS A HIGHLY CONDITIONAL THREAT WITH A MARKED INCREASED IN DEWPTS AND BACKED FLOW BEING NEEDED TO INCREASE THE POTENTIAL.

.@HDSweet99 Fort Wayne will be right on the western edge of the area of risk. It depends how far west the front moves.

If you live E of I-69 it is a good idea to make sure your NOAA Weather Radio is working before you go to bed tonight. Greatest risk 12a-6a

We have already discussed this evening who is available to come in overnight. Planning is especially important during an overnight event

The boundary that we are focused on has set up just east of Lima, Ohio at this time. We will need to continue to monitor if it moves west.

While we still have a small severe threat in a few counties in the SE don’t forget the flooding threat which covers a larger area.
— NWS Northern Indiana (@NWSIWX) May 14, 2014
Next batch of rain moving into the area. Another half an inch expected with this round.
— NWS Northern Indiana (@NWSIWX) May 14, 2014
High moisture content in the air tonight. This next round of precip has rain falling at a faster rate than earlier
— NWS Northern Indiana (@NWSIWX) May 15, 2014
These heavier rainfall rates are the reason for the flooding concern
